This is a false capture circuit or Lie detector circuit. The resistance of human skin using transistors and LED displays is small and easy application.

Portable Lie Detector Circuit and its Working - ElProCus

Depending on the changes in the person's skin resistance i.e if they sweats, it means they were lying. This is how the Lie Detector circuit works. TR1 and R3 form a buffer circuit which is called an emitter-follower. The voltage at the emitter of TR1 follows the voltage at the probe wire.
